Title: Liquid cooling apparatus
Inventor: ITAKURA MASATO
IPC: H05K7/20
Filed: 1996-04-18
Abstract: PROBLEM TO BE SOLVED: To obtain a liquid cooling apparatus which eliminates a fear that a Peltier element is damaged due to a rise in a pressure on the upstream side by installing an elastic body which urges the Peltier element to the side of a heat dissipating device via a tank. SOLUTION: When water is passed through a tank 16, a Peltier element 23 robs the water of heat via an aluminum plate 22, and the water which is supplied to a filter 26 is cooled. In the cooling water, fine dust particles and a fine foreign body component are removed by the action of active carbon inside the filter 26, and the water is discharged from a discharge port 27. However, the fine dust particles and the foreign body component close pores in the active carbon, and a rise in a pressure on the upstream side is generated. In this case, a passage which is formed of the tank 16 and the aluminum plate 22 is expanded due to the raised pressure.  However, the distortion of the tank due to its expansion is absorbed by a spring 24 due to the relative shift, of the tank 16 to a body 11, which is made possible by hoses 19, 20, and a load which is applied to the Peltier element 23 is not changed.

Title: Sheet pressurizing mechanism of automatic sheet feeding device
Inventor: IDETA NOBUHIKO
IPC: B65H3/06
Filed: 1988-04-19
Abstract: PURPOSE:To provide sure sheet feed for the sheet pressurizing mechanism of a slip feeding device by putting a friction plate in pressure contact at all times with a sheet feed roller, which is borne movably by another sheet feed roller borne movable in the direction toward the guide face of each sheet. CONSTITUTION:When sheets 10 for slips are set, a sheet feed roller 1 is pressed in the a direction by its own weight and a spring force through a friction plate 4. In this condition, the sheet feed roller 1 is fallen below the guide face 7 of sheet, so that setting of sheets can be made smoothly. At the time of sucking the sheets, the sheet feed roller 1 rotates in the b direction. The friction plate 4 in contact at this time generates a rotational load to cause application of a force to the roller 1 so as to roll in the direction of arrow C on the friction plate 4, and the sheet feed roller 1 is moved in the d direction. Thus the sheets 10 are separated from the undermost one and fed owing to friction with the sheet feed roller 1. This accomplishes sure sheet feeding.

Abstract: PURPOSE:To prevent the formation of films from an infrared absorbing substance on a protector and carry out properly the adjustment of the substrate temperature, by jetting molecular beams of a specific element with the protector provided near a peep hole for adjusting the crystal substrate temperature in a crystal growing apparatus with the molecular beams. CONSTITUTION:A crystal substrate 4 heated by a heater 6 is placed in an untrahigh vacuum vessel, and GaAs crystals are grown epitaxially with molecular beams of GaAs from a molecular beam source 7. In the process, the temperature of the substrate 4 is measured by an infrared radiation type thermometer 9 through a peep hole 8, and the heating temperature of the substrate 4 is properly controlled by using the obtained results. In this case, As of high vapor pressure is reevaporated from the substrate 4 and stuck to the peep hole 8, and the transmittance of the infrared rays is deteriorated to cause errors in the measured temperature value of the substrate 4. Therefore, a sapphire protector 11 is placed near the peep hole 8. Ga is irradiated from a molecular beam source 13 to form a GaAs film together with the reevaporated As. No error is caused in the temperature measurement of the substrate 4 due to 100% transmittance of the infrared rays by the GaAs film.
